My imagination ran wild as she bent over to pick up our dog, a young and small terrier. He had been jumping on her leg for only mere moments but she just couldn't stand it. As she bent over Cara revealed to me most of her creamy white turned sultry tanned young breasts that i had been teased with all summer long in the pool. My sister was only thirteen but fully mature in every way but mind. She didn't notice the way guys looked at her in school and the way I tried to catch glimpses of her at home. In the shower or getting ready for school. She didn't think that way, but I sure did. I would accidentally walk in on her getting ready in the morning with my boxers on. She would be standing  in the mirror doing her hair or something usually in a tank and some bikini cut panties. She always just yelled, "James, get outta here!" Easy mistake since we shared a bathroom. 
	I was sixteen and felt the need for a female touch. I had jacked off numerous times thinking about Cara and I wanted that to change. I was done with jerking off. I wanted the real thing. 	I had been on several dates this my sophomore year in high school. None ending like I wanted and my father expected. He was always talking about how he was such a stud in high school. nailing the senior cheerleader after football practice his sophomore year. That story repeated to me over the years was my mark for perfection, kind of unsettling since the head cheerleader ended up later on to be my mom. You could still see it in her. I bet she could still do the splits if she wanted to. To my friends she was definitely a MILF. 
	Today was Wednesday and our parents were going out of town this weekend to some  kind of conference for our dad's work. Was nice that he had a good enough job for them to pay for mom too. They trusted us to stay out of trouble. After all they would only be gone friday and saturday. Of course mom would have a neighbor check on us. I had only two days to plan my attack. I had to either trick or seduce her into it. After school I came home to find my sister laying out by the pool. Skin glistening and her bathing suit clinging to her beautiful full breasts and her nearly hairless pussy. I'm sure she kept it trimmed since I've never seen any sneek out. Lord I wish I had though. I walked up and sit down beside her on a lounger. Wanted to make sure i had a good angle to look at her body. "Hey Cara, did you hear?" I ask. "What about us being home alone this weekend. I sure hope you're not planning a party, I don't wanna get into trouble." she replied. "O nothing like that, thought we might catch a movie or something, how's that sound?" "That sounds fine; Hey James, can you rub lotion on my back when I turn over, I don't wanna burn." With my hands almost trembling I grabbed the bottle and put some on my hands. She slowly turned over revealing her bottom, she told me to undo her top so she wouldn't have a big line on her back and shoulder. So I did as I was told. I slowly ran up and down in a circular pattern the lotion on her back down to the small of her back just slightly above her bikini bottoms. "James." she said,"Can you get my sides to I don't wanna have an uneven tan." I started to do the side closest to me when she stopped me and said. "Just straddle me and get both at once." I stood over top of her and slid my hands up and down her sides from her armpit to her hips. Slowing down at the side of her breasts and at her nice hips. I was now sporting a huge boner. If she wasn't on her stomach she would be looking straight up at it. After that was done I told her I was gonna go change into my swimming trunks and go for a swim. God knows I needed to cool off. 
	I quickly walked over to the "shower shack" as I have called it for years and started to change into my trunks but the thoughts of her body, her breasts and her round plump ass made me drift off and fantasize about Cara. Those big natural at least large C cup breasts on that slender body all 5'6" of it with the light brown hair. I imagined large areola as I was partial to hopefully pink and huge nipples being hidden by that bikini. I had must been in there a while as Cara had gotten up and came over to the shack to see about me. She just opened up the door to my embarassment. Though there were no lights on just natural light beaming in I knew that she had seen my endowment before she covered her mouth and shut the door quickly. Saying sorry, I'm sorry as she walked away. I just pushed it down in my trunks and went on and took that swim. She had to have known why I was in there so long. Was she trying to come in on me?
	We all sit down for dinner that night. I couldn't help but notice that Cara kept looking at me right in the eyes. Half way through the meal she excused herself and immediately mom ask me if somwthing had happened today at school or something. "Not that I know of mom" I replied. She has been acting funny though. "James, why don't you go talk to her, you two have always been close." mom insisted. 
	I went upstairs and met a only partially opened door to her room. I noticed the shower being on and the clothes that she was wearing at dinner only moments earlier on the floor. I came up to her bathroom door slightly ajar and peeped in to see her figure in the frosted glass of our shower stall. She wasn't moving much to be taking a shower. Just as my thought ran through my head I heard her let out a little moan. She was playing with herself in our shower. I had done that so many times thinking about her. Now she was doing it thinking about me and my huge boner from earlier. Thoughts of her body flashed in my head and my boner from earlier reappeared. Then suddenly the water stopped. Silence. "Shit!!" I said in my head. I turned and ran out into the hallway. My hard on subsiding as I ran. I heard the door from the bathroom creek a little and I suspisciouly strolled into the room just as she had dropped her towel to put on her night clothes. She stopped, I stopped. I stared at her. 
	She was just as I imagined. Standing there still slightly wet from her shower and undoubtedly her finger banging session. She was beautiful 5'6" slender but with huge breasts that hung perfectly on her frame. Her areola wasn't big as I had hoped but wow. Her nipples hard and dark pink were huge. Her hips jutted slightly out and between those beatifully tanned legs was a magnificent trimmed although very young bush, light brown in a sort of triangle shape. I couldn't say anything. I just stared. Then she broke the silence. "Seems as though you liked what you felt of earlier huh?" I couldn't believe that she had talked first. What surprised me was that she didn't try to cover up at first. "You can stop staring now, and talk." Cara muttered to me. She grabbed her tank and her white shorts and put them on. "Now can you talk James?" she asked. I didn't know what to say or at least how to say it. She then said, "I thought you should see me since you've been trying for so long. And after I got to see your cock today I was like well I've seen him guess it's only fair for him to see me." 
	I felt like rushing over to her and taking her up in to my arms. Grabbing her passionately giving her deep french kisses and then kissing all the way down from her mouth, neck, breasts, stomach and then her young virginal pussy. But I knew that this was not the time for all of that. Mom and dad were downstairs in the dining room and would undoubtedly be up here soon since neither one of us had come back down. So I ended my long look at her and went back downstairs. Meeting our parents at the end of the steps I said, "Her stomach was bothering her, she is fine." 
	Cara came back down the stairs a few minutes later. She laid down in front of the couch almost directly in front of me. Mom and dad were almost past out on the other side of the couch. So I ended up flipping through the channels until I found one of those so stupid it's funny kind of movies on HBO. These movies almost always had nudity in them and since this afternoon that was all I could think about anyway. It wasn't long until it came to a good part. Actually a girl laying out on a beach topless. Cara said almost jokingly, "I will have to try that some day." In my mind I was thinking God I hope so. So we finished the movie and it was about 1030pm. Cara decided to go to bed and I ended up waking mom and dad up to tell them to do the same. 
	Cara had been in the bed for a few minutes  when i went to the bathroom to take a piss before going to bed. While I was pissing I heard her door creek open. "Whatcha doin?" she asked. Knowing the answer. "I'm pissing, what you think I'm doing?" Thought you might have been jerking off in here thinking of me!" she rebutted. "See you're not always right like you think you are." She watched me the entire time I pissed. Even when I was shaking it. "I think you liked the way my cock looked today." She walked up and stood right beside of me grasping my limp cock in her hand which immediately started to respond to her touch. "I don't think its fair that you didn't get to relieve yourself today, so I am going to do it for you."
	Cara had a firm hold on my cock which was hard as a rock now. She slowly started to stroke it in an up and down motion as i stood in the middle of the bathroom. "You're dick is so big and thick when it gets hard, I may have to use two hands" All I could muster was slight grunt as she continued to stroke my cock. I was sure she hadn't done even this before but she wasn't timid at all. She stroked faster and faster. It felt so good, she even once spit on it to lube it up. She must have seen it in a porn or something. She was leaned over at the head of my cock looking at my piss hole. Her breath was so warm on my cock. I couldn't take it any more. I had to release my load. Without warning I shot 6 big shots of my thick load out. A couple got on her shirt and the others the floor. She stared with big bold eyes at my cum on her shirt and the floor. Then out of no where she looked back at my cock took her tongue and licked the last little drop of my head. "Mmmm salty." she said. "Now is that what you were trying to do after rubbing that lotion on me today?" I just shook my head out of breath. She took her shirt off wiped off the floor and stuck it in the hamper.
